ALSTOM has confirmed the appointment of Martin Sion as the company’s new CEO, who will take up his new post on April 1 2026.
Alstom’s board of directors confirmed the appointment on October 8, based on the recommendations of the company’s nominations and renumeration committee.
Sion has spent his entire career in the aerospace industry, most recently as CEO of Ariane Groupe, which he has led since 2023. He has also served as chairman of Safran Electronics and Defence, and as CEO of Aircelle (now Safran Nacelles). Sion is a graduate of École Centrale de Paris.
“The board has conducted an extensive search process over the last few months, and we believe that Martin Sion has the necessary experience to lead Alstom,” says Philippe Petitcolin, chairman of Alstom’s board of directors.
“We look forward to welcoming him in April 2026. Until then, Henri Poupart-Lafarge will continue in his role, thus ensuring a smooth transition.”
According to Alstom, Sion will receive an annual salary of €1.05m, a signing-on bonus worth €1.2m, annual performance-related benefits that could total €1.8m, and a loyalty bonus.
Sion succeeds Poupart-Lafarge who announced that he would not seek a fourth term as CEO in May. Poupart-Lafarge was appointed as CEO of Alstom in February 2016 when the company became solely focused on the rail market, having served as CEO of Alstom Transport since 2011.
